Single-segment speed run of Castlevania II: Simon's Quest done during September 2003. Available in three versions: low quality, normal quality, and 60 fps high quality.
Author's comments: This has been done faster by other gamers, but this was once the top TG run for roughly a year and a half. It features a simple (if not always fast) path through the game, while collecting a minimal amount of items. Just don't ask me why I got the Sacred Flame weapon, but never used it. :)
I spend a ton of time wandering around, but this is mostly because I need to wait until daylight to go to the towns and get the necessary weapons. Faster runs will avoid getting as many of the whip upgrades, but I was playing it safe here.
I died during an unlucky fight with the Grim Reaper, while going for the Golden Knife. I could have done without that, but the Golden Knife makes future boss battles super-easy.
